Size difference for the enclosure for MPZ vs. MPZB Mini Power Zone products
Applies to Mini Power Zone Transformers by SquareD/Schneider Electric
The MPZ products use a QO Load Center Interior, the MPZB products use an NQ Panelboard Interior
No. The MPZB devices for use with bolt on breakers are larger than those that use the plug on breakers. The top transformer section is the same size on both, but the bottom load center section is taller for the bolt on type units.
